IMPROVED SMUT-MAOHINE.

' TO ALL WHOM IT-MAY G ONOERN:

dust from the grain.

Be it known that LEENRY STANLEY, of St. Johnsbury, in the countyof Caledonia, and State of Vermont,

have invented a new and useful Improvement in Smut-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use these-me, reference being had to the accompanyingdrawings, forming part of this specification.

I The nature of this'invention relates to improvements in smut-machines, the object of which is to provide a more effective machine than those now in use.

It consists of an arrangement of fan-blowers within cases, which are curved around the fans in the form of scrolls, into one of which the grain to be cleaned is admitted through the air-passage of the fans, and from which it is forced by the blast of air around the scroll, the sides of which are perforated, to the mouth, into i spent communicating with the next fan-chamber, and in like manner forced from there to the mouth of the scroll, when it encounters another blast of airfrom another fan, which is designed toseparate the chad, as will be more fully described on reference to the accompanying drawings, wherein- Figure 1 represents a sectional elevation of my improved machine, with a part broken away, and

Figure 2 represents a front elevation of the same.

Similar letters of reference indicate corresponding parts.

A represents the frame, whercon the fan-cases, B and C, are arranged in a vertical plane, the sides of which, and the partition between them, being preferably made of sheet iron.

The circumferential easing, D, is made of erforated sheet metal or screen-wire, and may be continued around the fan-chambertwo or more times, forminga scroll-passage, through which the grain iscarried by the blast to the mouth.

E represents a spout, communicating from the scrollof the case 0 to the fan-chamber of the case B, as shown at E, in fig. -1. I i i G represents a curved spout, connected to tho moutlrof the scroll of the case B, provided with the wirescrcencovcring, .H, at the point of the curve, where the blast will have the greatest effect for separating the The spout E is also provided with a similar screen-covering, H, arranged in a similar position with reference to the curve in that spout.

I represents a detached fan-blower, with a pipe communicating with the dclivering ispout G, for separating the chail from the grain, and for assisting the delivery of the grain from the scroll B by suction.

Two or any other number of fan-chambcrs and scrolls may be'arranged together, as described.

K represents a hopper, into which the grain is fed to be delivered to the fan-chamber of the scroll A, where, it encounters the action of thefan of that chamber, and is forced around the scroll to the passage E, by which it is effectually scoured, the dust separated from it thereby being forced through the perforations of thocuge;

From the mouth of the passage Eit is forced into the fan-chamber of the case B, encountering on its waythe screen H at the abrupt curve of the spout, where the separation of dust is facilitated.

From the said fun-chamber it is again forced around, in a similar manner, the scroll of the case B into the delivering-spout G, and against the screen H in the abrupt curve of the same.

.From the spout G to the receiver of the grain there may be a broken communication, whereby the blastbrought to bear on the grain at this po'int by the fan I may separate the chat? and other similar matter from it, while at the same time facilitating the discharge of the grain from the scroll B-by the suction prod-ueedtherein.

All the fans of a scricsmay be set upon on e shaft, or they may be, ifpreferred, set upon separate shafts. An outer casing of shcet metal may, if preferred, be provided around the perforated scroll, for the reception of the dust, which may be removed therefrom by a fan suitably arranged.

I claim as new, and desire to secure by Letters Patent- The grain-cleaning machine, composed of one or a series of perforated scroll-cascs, surrounding ono or more fans, the spouts E G, undjthe fan I, arranged substantially as and for the purpose described. I

. HENRY STANLEY.
